Car Key Fob Repair - How to Get Back on the Road Even If Your Keyless Entry isn't Working
Over time, key fobs can have issues, such as a malfunction. Some issues may need professional attention, but most are fixable at home.
The first step is generally to replace the battery. Most fobs use flat watch-style batteries which are easily found at hardware stores or auto parts stores.
Dead Battery
When a key fob battery dies, it can be a huge inconvenience particularly if you're away from home. There are ways to get back on the road even the car's keyless entry isn't working.
One of the first things to check is whether the key fob's buttons still function. If they do, the issue may be with the car's locks instead of the fob.
If your keys don't work, look for a key slot with a mechanical lock located in the trim of your door handle or in another location on the car (consult the owner's manual). Insert the mechanical key and try again. If this fails to unlock the door, some vehicles have an app that allows you to unlock it remotely. FordPass Connect MyChevrolet Mobile Application and myMazda apps, for instance, allow owners to unlock their doors using their smartphones. These apps charge a monthly subscription fee.
It is also important to ensure that your key fob isn't draining your car's battery by being plugged into it. A dead fob can drain your battery quickly particularly if it's used to control your phone or TV while you are watching.
A key fob that's low on battery can sometimes be started by holding it up to the start button. It's a simple fix that will save you a trip to the dealership or to select Interstate All Battery Center locations.
If your key fob doesn't work try testing it in a vehicle that has an electronic starter button. If it doesn't, you may need to replace the fob battery. This is why it's a good idea to keep an extra key fob in the bag or purse.
Damaged Buttons
If your key fob is unable to open doors or start the vehicle remotely, it's possible that one or more of its buttons is damaged. Your key fob contains an electronic circuit that has "contact pads" that are covered with an electrically conductive film. The film wears off over time. This wear can cause your fob to respond slower or not at all.
The pad that contacts the car keyfob is easily replaced with an flat-head screwdriver. If the case is damaged or badly smashed, it will be difficult to open. You'll need to take it to an auto repair shop to have the fob repaired.
It's not unusual for a key fob to be dropped on hard surfaces, trodden on or exposed to water. These incidents can cause physical damage, including bending and snapping the keys.
This can also alter the internals of the fob and could cause an issue. It's a good idea therefore, to always carry an additional fob in your purse or pocket in the event that the one you're currently using breaks.
Examine the battery first to determine If your key fob's buttons are not responding in the way they should. Key fobs don't require any special electronic device. They utilize the same battery for two dollars that is used in hearing aids and watches. They are sold at hardware, drug, and online stores.
If the battery is in good condition the buttons could be worn or dirty. You can easily clean them using a damp cloth. If they're still not responding, you can test a different key fob to determine whether the issue is related to yours or with a particular type of car key fob. If the other key fob works it is possible that yours needs to be reset or replaced.
Reprogramming
The world of fobs for car keys is more complex than many myths suggest. Basic fobs operate with radio frequency signals that are specific to each vehicle. The fobs need to be programmed correctly to unlock and start the vehicle. Reprogramming a key fob not as easy as pressing several keys. It's usually handled by the dealer.
The procedure for reprogramming the fob is dependent on the manufacturer and model year of your vehicle, so it's important to read the owner's manual to get step-by-step instructions. Certain manufacturers, like Mercedes have their own proprietary technology that guarantees only dealerships can design a new fob and re-sync it to your vehicle. However, some independent shops can offer this service as well so make sure to review reviews and prices prior to choosing the right shop.
Some car models will wipe out all other fobs when they're programmed, meaning you'll need to get any additional fobs professionally programmed. This is an expensive proposition particularly if you're down to one functioning fob. It's always recommended to have at minimum a spare mechanical key that you can use to open the doors and trunk even if it doesn't start the car.
Be prepared for a difficult experience if you opt to reprogram your fob by yourself. There are countless guides on the internet that promise success, but you'll likely be disappointed. A lot of these guides were written by people with no experience and are based on unsubstantiated claims. Some even claim that you can program your own car key fob in only a few clicks, which is extremely false.
The battery is usually held in place by an elastic clip that can be easily removed. However the circuit board is home to the battery, and you will need to carefully remove the battery with a tool. You should be able to find the button cell battery. This is usually tiny batteries for watches that you can purchase at most home improvement or pharmacies. Removing the battery is typically a straightforward procedure, and it's always a good idea to test first before replacing the entire unit.
Replacement
If a car key fob is damaged or has stopped working it is crucial to know that there are several ways to remedy the problem. An easy fix could be as easy as replacing the battery or reprogramming the key fob, but a more in-depth repair may be needed. A spare fob is useful in the event that one is stolen or lost.
Most modern key fobs include an incredibly small physical key in addition the electronics they use, which makes them both more expensive and more complex to replace than traditional keys. Some "smart fobs" even come with remote starters. It's therefore important to know that it can take up to an hour to get an alternative key fob cut and programmed to your vehicle.
Fobs communicate with the car's receiver by using a small radio transmitter that is mounted on the circuit board. Pressing the button triggers the transmitter, which transmits an RF signal that is unique to the car's receiver. The receiver detects the signal and checks it against preprogrammed codes. This allows the driver to start the car from a distance, without having to put the key in the ignition.
If your key fob buttons are not responding or working intermittently, they may be damaged by water. You may be able to repair the fob by removing it and examining it for broken or non-responsive buttons. If this does not solve the issue, you can try reprogramming the fob or purchasing an entirely new fob.
It is recommended to consult a local auto dealer or a locksmith prior purchasing a replacement keyfob to ensure it is compatible with the security system of your vehicle. There are many aftermarket fobs cheaper, but it's essential to research the brands and read reviews before attempting to program them. While repair car keys are able to be replaced by a reputable locksmith, others require special equipment for programming that can only be used by a professional auto dealer or auto technician.
